  • I would suspect something in the neighbourhood.

    I think I saw something like that with a power supply that was very quickly chopping and changing the frequency it was operating the primary transformer at. All of the peaks seen appear to be spaced identically in the frequency domain, with a broadband pulse on most of the changes.

    Was there an unusual electric car nearby when this signal was seen/heard?
